OneFlow, the better alternative to a water softener
OneFlow® is the environmentally-friendly way to prevent scale buildup. Through Template-Assisted Crystallization (TAC), dissolved hardness minerals in the water join together, forming microscopic crystals on the surface of the OneFlow media. Once formed, these crystals detach from the media and flow freely through the plumbing system, unable to form hard scale on internal plumbing surfaces.

water heaters
Without scale buildup on the
heat exchanger, your water
heater can efficiently transfer
energy to the water, keeping
energy bills in check.
bathroom fixtures
Make scrubbing and polishing
a thing of the past. Soap and
